Module::Mask 0.03

Sometimes you need to test what happens when a given module is not installed. Module::Mask is a Perl module that provides a way of temporarily hiding installed modules from perl's require mechanism. The Module::Mask object adds itself to @INC and blocks require calls to restricted modules.<br /><br />Module::Mask will not affect modules already loaded at time of instantiation.<br /><br />SYNOPSIS<br /><br /> use Module::Mask;<br /><br /> {<br /> my $mask = new Module::Mask ('My::Module');<br /> eval { require My::Module };<br /> if ($@) {<br /> # ... should be called<br /> }<br /> else {<br /> warn "require succeeded unexpectedly"<br /> }<br /> }<br /> <br /> # The mask is out of scope, this should now work.<br /> eval { require My::Module };<br /><br /> # There's also an inverted version:<br /> {<br /> my $mask = new Module::Mask::Inverted qw( Foo Bar );<br /><br /> # Now only Foo and Bar can be loaded by require:<br /> eval {require Baz};<br /> }
